don't allocate serial_ops
Now that struct serial_ops is const everywhere, we can easily turn the instances into globals. This patch implements this idea. On the one hand I think this is nicer since it makes a bit more data readonly and slightly reduces allocations. On the other hand it reduces readability somewhat. If the readability is a concern to anyone I was thinking I could write a macro that conditionally uses GCC's designated initializer extension. Tested by rebuilding on x86-64 Fedora 18, both natively and using the mingw cross tools. 2013-12-19 Tom Tromey <tromey@redhat.com> * ser-unix.c (hardwire_ops): New global. (_initialize_ser_hardwire): Use it. * ser-tcp.c (tcp_ops): New global. (_initialize_ser_tcp): Use it. * ser-pipe.c (pipe_ops): New global. (_initialize_ser_pipe): Use it. * ser-mingw.c (hardwire_ops, tty_ops, pipe_ops, tcp_ops): New globals. (_initialize_ser_windows): Use them.
